You could almost take that to the bank. It still has the rubber boot and a separate ground strap, which pretty much went away with the syncro spark. I'm sure TKG or BCCHI might chime in soon with more accurate background. I do not believe Gary ever made ignitions, but may have used products from makers other than CH. It's definately not anything late model that might have entered service shortly before the Kangke take over of the company.
